What is an example of a baryon that isn't a proton or a neutron?

Expert Solution

Elementary particles are primarily classified as leptons and hadrons. While hadrons take part in strong interactions (one of the four interactions in nature), leptons do not respond to this interaction. A hadron is a particle with structure and is composed of quarks while leptons are structureless and are considered fundamental particles.

A hadron may be composed of either two or three quarks. Hadrons that are composed of three quarks are called baryons and those with two quarks are known as mesons. While baryons have half-integral spin (1/2, 3/2,...) mesons have integral spin (0,1,2....).

Apart from proton or neutron, sigma particles (), cascade particles (), lambda particle (), delta particles (), omega particle () are other baryons.

How would you determine the number of proton-proton pairs, the number of neutron-neutron pairs, and the number of neutron-neutron pairs in an atom given its atomic number and mass number? Hence show that Carbon has 15 proton-proton pairs and 10 neutron-neutron pairs.

Consider a neutron as consisting of a proton plus a π- meson in an l = 1 orbital state. What would be the orbital magnetic dipole moment of such a configuration? Express your resultas a multiple of the proton’s magnetic moment.

If you drop a proton and a neutron in a gravitational field, they both fall, but the proton has a charge and accelerating charges radiate energy, so that leaves less kinetic energy for the proton and by this reasoning, it should fall more slowly than a charge-free object. The issue is discussed but not in the terms above in Peierls's "Surprises in Theoretical Physics" in the chapter "radiation in hyperbolic motion", but I didn't understand the chapter well enough (or...

(a) You decided to turn a neutron into a proton. Making sure that the charge is conserved, you wrote down n → p + e-. When you actually did the experiment, an antineutrino came out in addition, making the actual interaction n → p + e -+ ¯ν. Among what needs to be conserved, what was not conserved in the interaction without the antineutrino? (b) You managed to capture the emitted electron inside of a one-dimensional infinite potential well with...

Outside the nucleus, the neutron itself is radioactive and decays into a proton, an electron, and an antineutrino. The half-life of a neutron (mass = 1.675 × 10-27 kg) outside the nucleus is 10.4 min. On average, over what distance x would a beam of 5.55-eV neutrons travel before the number of neutrons decreased to 75.0% of its initial value? Ignore relativistic effects.

The deuteron is a bound state of a proton and a neutron of total angular momentum j = 1. It is known to be principally an S(ℓ = 0) state with a small admixture of a D(ℓ = 2) state. Calculate the magnetic moment of the pure d state n-p system with j = 1. Assume that the n and p spins are to be coupled to make the total spin s which is then coupled to the orbital angular...

Please solve this conceptual question. In positron decay, a proton in the nucleus becomes a neutron and its positive charge is carried away by the positron. A neutron, though, has a larger rest energy than a proton. How is that possible?
